Plastic damage of REBCO (REBaCuO, where RE=rare earth) coated conductors by screening current stress (SCS) is a significant concern for ultra-high-field superconducting magnets. Indeed, the third Little Big Coil (LBC3), a REBCO magnet that generated a record, high field of 45.5 T, showed wavy plastic damage produced by excess SCS in all pancakes except two made with single-slit conductors having their slit edges pointing inward towards the magnet center.

Our objective was to compare AOTMiT (Polish: Agencja Oceny Technologii Medycznych i Taryfikacji) recommendations to other HTA (Health Technology Assessment) agencies for newly registered drugs and new registration indications issued by the European Medicines Agency between 2014 and 2019. The study aims to assess the consistency and justifications of AOTMiT recommendations compared to that of other HTA agencies in 11 countries. A total of 2496 reimbursement recommendations published by 12 HTA agencies for 464 medicinal products and 525 indications were analyzed.

Currently, expanding concepts concerning the pathophysiology of GBM are inextricably linked with neuroinflammatory phenomena. On account of this fact, the identification of novel pathomechanisms targeting neuroinflammation seems to be crucial in terms of yielding successful individual therapeutic strategies.

Many-body localization (MBL) is a widely studied mechanism for thermalization to fail in strongly disordered quantum systems, but it is still not understood precisely how the range of interactions affects the dynamical behavior and the existence of MBL, especially in dimensions D > 1. By investigating nonequilibrium dynamics in strongly disordered D = 2 electron systems with power-law interactions ∝ 1/r and poor coupling to a thermal bath, here we observe MBL-like, prethermal dynamics for α = 3.

A direct consequence of the Weyl state is the layer dependent Chern number, [Formula: see text]. Previous reports in MnBiTe thin films have shown higher [Formula: see text] states either by increasing the film thickness or controlling the chemical potential.

Aim: In January 2017, a new funding model for diagnostic genetic testing in cancer was introduced in Poland.
Objectives: The aim of this study was to assess the impact of changing the funding model for genetic diagnosis in oncology on improving access to personalized medicine in Poland between 2017 and 2019.
Methods: The analysis included data on settlements with the National Health Fund for genetic tests in cancer under a contract of the hospital treatment type and under the contract in the type of separately contracted services between 2017 and 2019.
Background: Cardiovascular diseases are associated with growing public and private expenditure on healthcare regardless geographic region. Therefore, it is necessary to accurately estimate the overall societal costs-both direct and indirect expenses from the perspective of patients, caregivers and employers.
Research Design: The aim of this paper is to determine the direct and indirect costs related to cardiovascular diseases in Poland from 2015 to 2017.
Background: In Poland drug programmes developed by the Minister of Health and financed by the National Health Fund are special reimbursement frameworks of innovative, expensive, and mostly hospital based medical products used for a small number of patients.
Research Design: The research presented in this paper is based on data analysis published by the National Health Fund in Poland. The analysis focused on estimating public payer expenditure on drugs available within drug programmes from 2015 to 2018.
Strong magnetic fields are required in many fields, such as medicine (magnetic resonance imaging), pharmacy (nuclear magnetic resonance), particle accelerators (such as the Large Hadron Collider) and fusion devices (for example, the International Thermonuclear Experimental Reactor, ITER), as well as for other diverse scientific and industrial uses. For almost two decades, 45 tesla has been the highest achievable direct-current (d.c.

Although in Europe the volume of produced cytotoxic and cytostatic waste (used in chemotherapy by oncological patients) has been declining for several years, in Poland a reverse trend has been observed. As this waste puts the safety of medical workers and patients at risk, special handling procedures are required to limit the harmful effect of these drugs on human health.

One major challenge has been to arrive at a satisfactory understanding of the unusual metallic "normal state" from which the superconducting state emerges upon cooling. A second challenge has been to achieve a unified understanding of hole- and electron-doped compounds.

Background: According to the current data, around 1% of the Poland population have epilepsy, which comprises about 400,000 people. This group of patients requires life-long therapy including both drug therapy and hospitalization. The character of the epilepsy has a significant impact on the expenses borne by individual patients, and the prevalence of the disease has a significant impact on the health care system.

We performed a feasibility study on a high-strength Bi Pb SrCaCuO (Bi-2223) tape conductor for high-field solenoid applications. The investigated conductor, DI-BSCCO Type HT-XX, is a pre-production version of Type HT-NX, which has recently become available from Sumitomo Electric Industries (SEI). It is based on their DI-BSCCO Type H tape, but laminated with a high-strength Ni-alloy.

However, superconducting wires for high-field-magnet applications are still dominated by low-T NbSn due probably to cost and processing issues. The recent discovery of a second class of high-T materials, Fe-based superconductors, may provide another option for high-field-magnet wires.
